Biological waste water treatment
{"Image DocumentName": "Biological waste water treatment", "Image ImageDescription": "It is a type of waste water treatment in which microorganisms such as bacteria are used to remove pollutants from waste water through bio-chemical reaction. Classification of biological Waste water methods. Suspended and attached treatment. Aerobic and anaerobic. Suspended growth process is a biological w.w.t in which microorganisms are maintained in suspension while converting organic matter to gases and cell tissue (Activated sludge). Attached growth is a biological w.w.t in which microorganisms responsible for the conversion of organic matter to gases and cell tissue are attached to some innert material such as rocks, sand, or plastic (Trickling filter). Aerobic: biological treatment is a process in which the pollutants in the waste water (organic matter) are stabilized by microorganisms in the presence of molecular oxygen. Anaerobic: biological treatment is a process in which the pollutants in the waste water (organic matter) are stabilized by microorganisms in the absence of molecular oxygen.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
